STEAM BOILER.

Application filed June 18,

This invention relates to new and useful improvements in steam boilersot the 'flash type that is wherein the steam is instantly generated uponthe contact ot the water upon the hotl plate of the boiler and that isarranged directly above a suitable burner or heat producing device.

ltn carrying out my invention there is pro vided a highly novel, simpleand relatively inexpensive steam boiler wherein steam may be rapidly andinexpensively generated and wherein the boiler is equipped withsuperheating coils arranged in spaced relation around the interior ofthe boiler.

ltn the drawings wherein like reference ch a ra eters indicatecorresponding` parts throughout the several views:

Figure 1 is a det-ail vertical section through my improved boiler, and

Figures 2 and 3 are horizontal sections taken substantially upon thelines 2-2 and -loit Figure 1.

New having' particular reference to the drawings, 5 designates acylindrical jacket open at its opposite ends and within which ends arearranged upper and lower mani- `told heads (l and 7. rlhe upper head 6coinprises a pair ot spaced circular walls 7X and S termed at theiredges with downwardly eX- tending flanges 7 and 8', the lower wallbeing' arranged within the :flange 7 ot the top wall 7X and said tlangesbeing intercoimected and anchored to the upper' end o't the jaeliet 5 byrivets 9.

The lower manifold head consists ot inner and outer circular walls 10and 11 which are also :flanged as at 10 and 11', the lower wall 11 beingarranged within the tlann'e 10 of the inner wall 10 while both oi saidwalls are arranged within the lower end olf the jacket 5 and theirflanges interconnected and con-- nected to the lower edge ot the jacketby rivets 12. 'lf he inner walls 8 and 1() ot the heads G and T aretermed centrally with enlarged. circular openings within which arearranged and secured the opposite ends o1 a steam tube Arranged upon theouter sides o1 the 1927. Serial No. 199,710.

outermost walls 7X and 11 oit the heads G and 7, respectively, arereinforcing plates 13X and 14;, said outer walls being intercormectedand braced by long stay bolts 15, the ends of which project through theplates 13X and 14 and are headed as at 16.

Arranged at spaced points between the jacket 5 and steam tube 13 arevertical .steam superheatint,r coils 17 the opposite endsw ot which havecommunication with the interior oft the heads 6 and 7 ot the boiler.Further'- more arranged through the walls 10 and 11 oi' the lower headare ilues 18 to permit the products ot combustion trom a burner or thunebeneath the boiler to pass into the boiler between the jacket 5 and saidsteam tube 18 with the result that the steam passing th rough, the coils17 will be superheated.

A suitable inlet tor the water and an exhaust 'tor the steam areprovided, the saine being designated by the reference characters ll) and20, respectively. Apertures 21 in the casing 5, all'ord outlet tor theproducts ot combustion.

]}lavinf,1 thus described the invention, what I claim as new is ln aboiler ot the cha 'acter described, an open ended jacket, a steammanifold located within the upper end of the jacket, a water `manifoldlocated within the lower end ot the jacket, said n'ianiiiolds eachconsisting,r of inner and outer plates spaced apart and having lappedl'flanges connected together and to the jackets, a tube arrangedintermediate the inner 'walls of said manifolds and havingcornlminication at its opposite ends with the interiors ot saidmanifolds, heat 'ducs extending between the walls ot the water manifold,steam coils arranged between the inner walls ot the manifolds and havingcommunication therewith, plates arranged at the outer sides of theout-er walls o't' the manifolds, and stay bolts extending through thesaid manifold connecting` tubes and connected to said plates.

In testimony whereof I atlix my signature.
